I have an assignment in class where the question says to edit a file in pam.d directory to allow any users to access system-config-usrs program without being prompted for root password. After a while of trying to figure it out my teacher gave me the hint that the file is password-auth. However I couldn't figure out what to edit in that file. I think it had to do something with pam_permit.so but I tried many different edits and the usrs are still being prompted for root password.
here's the password-auth file below. I know it seems like cheating but I'm trying to learn here. So can anyone help me out with this?
